riaksearch performance, row limit, sorting not necessary

Hi list,

I'm wondering how riaksearch performance will degrade as I add documents.

For my purpose I limit rows at 1k and sorting is not necessary.  I have a
single node cluster for development.  I know I can increase performance if I
add nodes but I'd like to understand this before I do.

My documents are small ~200 bytes.  With an index of 30k and rows limited to
1k, no problems.  I added 100k documents, and then I hit
the too_many_results error.  Since I still have my row limit set at 1k, this
indicates that the query does not return as soon as it finds the first 1k
hits.  Is there a way to short circuit my queries so that they don't have to
scan the whole index?

I got around too_many_results by increasing my max_search_results (I read
https://help.basho.com/entries/480664-i-get-the-error-too-many-results).  I
wonder, though, if I'll keep bumping memory boundaries as I add a few
million docs to my index.

Thanks,
Daniel
